Galling and dust blowing and sucking device for coating of inner wall of pipeline

Abstract

The invention provides a galling and dust blowing and sucking device for a coating of the inner wall of a pipeline. The device comprises a main pipe body, a walking mechanism, a galling device, a dustblowing pipe, a dust sucking pipe, a cleaning device and a main controller. The walking mechanism drives the galling device, the dust blowing pipe and the dust sucking pipe to move on the inner wallof the pipeline along the axis, a main rotary motor drives the galling device, the dust blowing pipe and the dust sucking pipe to move on the inner wall of the pipeline along the circumference, the inner wall of the pipeline is stably galled through the galling device, intense blowing airflow is generated by the dust blowing pipe, abrasive dust left after galling is completed is blown up, the abrasive dust is sucked through the dust sucking pipe, cleaning liquid is sprayed on cotton cloth a wiping cloth single unit through a liquid sprayer, the cotton cloth makes contact with the inner wall ofthe pipeline for wiping, the abrasive dust left after galling is completed is effectively removed, the cleanliness of a grinding surface is greatly improved, the surface with the uniform and stable roughness is obtained on the inner wall of the pipeline, adhesive force between two coatings is improved, the spraying effect is improved, and the corrosion resistance of the inner wall of the pipelineis improved.

Description

technical field [0001] The invention relates to a pipeline coating treatment device, in particular to a pipeline inner wall coating roughening and soot blowing and dust suction device. Background technique [0002] Steel structures play an important role in ships and buildings. Steel pipes are a very common steel structure and are widely used. In order to prevent corrosion, the outer wall and inner cavity of the steel structure need to be coated. In order to improve the anticorrosion effect of the corrosion-resistant coating, multiple coatings are usually applied. In order to improve the bonding degree between the coatings, the current coating Before the next coating is applied, the roughening process is carried out to increase the roughness of the coating and eliminate defects such as orange peel and small sagging. However, due to the narrow space of the inner wall of the pipeline, the inner wall of the pipeline is rarely roughened in the industry at present, resulting in ...
